Conscious Awareness of Facial Stimuli as a Function of Attentional, Time and Contextual Constraints

Nega, C. (2001). Conscious Awareness of Facial Stimuli as a Function of Attentional, Time and Contextual Constraints. (Unpublished Doctoral thesis, City, University of London)


The present research inquired the functional dissociation, that different independent variables produce, between the two states of conscious awareness, measured by remember and know responses. The experimental work used a divided attention task, and two contextual manipulations, a perceptual one and a conceptual one.

The findings from the divided attention task showed the selective influence on remembering whereas knowing remained unaffected across conditions. Furthermore, the observed dissociation was maintained in varying divided attention tasks, that is, tone counting (Experiment 1 and 2) and story listening (Experiment 3).

The overall findings from the manipulation of context was that study/test compatibility increased only remember responses whereas know and guess responses maintained similar levels of performance. However, the effect of context disappeared under rapid presentation rates, namely 300 and 700msec. This pattern of dissociation between remembering and knowing was preserved in both perceptual manipulations, that is, modification of size in Experiments 4 and 5, and conceptual manipulation, that is, alteration of word cues in Experiments 6 and 7.

The obtained results are discussed in the light of the conceptual/perceptual theory, the distinctiveness/fluency theory, the signal detection theory, and the multiple memory systems theory.
